These pictures show us another example of why car maintenance is so important. We all have the habit of putting off maintenance services because everything else is more important or we are afraid of the potential cost involved.
The first picture is of a differential that has moisture in the gear oil. The second picture compares fresh clean gear oil (on the left) and contaminated oil (on the right--from a different vehicle).
It is easy to see what happens to gear oil over time. When moisture is added in, you get that muddy color as well. With a little extra time, we can clean it all up and get the vehicle back in service.
When was the last time your differential, transmission, and transfer case fluids were serviced?
Maintenance really is the key to keeping your vehicle on the road for a long time!
